Abstract:
|
PURPOSE: To investigate the association between exposure to
traffic-related air pollution and use of spectacles (as a
surrogate measure for myopia) in schoolchildren. METHODS: We
analyzed the impact of exposure to NO2 and PM2.5 light
absorbance at home (predicted by land-use regression models) and
exposure to NO2 and black carbon (BC) at school (measured by
monitoring campaigns) on the use of spectacles in a cohort of
2727 schoolchildren (7-10 years old) in Barcelona (2012-2015).
We conducted cross-sectional analyses based on lifelong exposure
to air pollution and prevalent cases of spectacles at baseline
data collection campaign as well as longitudinal analyses based
on incident cases of spectacles use and exposure to air
pollution during the three-year period between the baseline and
last data collection campaigns. Logistic regression models were
developed to quantify the association between spectacles use and
each of air pollutants adjusted for relevant covariates.
RESULTS: An interquartile range increase in exposure to NO2 and
PM2.5 absorbance at home was respectively associated with odds
ratios (95% confidence intervals (CIs)) for spectacles use of
1.16 (1.03, 1.29) and 1.13 (0.99, 1.28) in cross-sectional
analyses and 1.15 (1.00, 1.33) and 1.23 (1.03, 1.46) in
longitudinal analyses. Similarly, odds ratio (95% CIs) of
spectacles use associated with an interquartile range increase
in exposures to NO2 and black carbon at school was respectively
1.32 (1.09, 1.59) and 1.13 (0.97, 1.32) in cross-sectional
analyses and 1.12 (0.84, 1.50) and 1.27 (1.03, 1.56) in
longitudinal analyses. These findings were robust to a range of
sensitivity analyses that we conducted. CONCLUSION: We observed
increased risk of spectacles use associated with exposure to
traffic-related air pollution. These findings require further
confirmation by future studies applying more refined outcome
measures such as quantified visual acuity and separating
different types of refractive errors. |
